Effluent discharge locations for motorised caravans: a GIS analysis for the South Island New Zealand

Abstract

Freedom Camping has gained popularity in New Zealand in the last decade. This has created the potential for consequential environmental problems. Various public sectors are concerned about the disposal of untreated sewerage commonly disposed besides roads, in rest places and in streams and rivers. At the same time campervan travellers have expressed frustration because there are limited public effluent disposal facilities situated around New Zealand.

Members of the New Zealand Motor Caravan Association Incorporated (NZMCA) completed surveys detailing their travel patterns and travel behaviour. Data was modelled and analysed using a Geographic Information System, to determine locations where public disposal facilities were required.

Research indicated that this issue is complex and there are many factors involved, which determine whether travellers discharge of effluent legally, or not. Recommendations include introducing an awareness program to educate travellers about potential environmental and health hazards associated with illegal effluent discharge. Information also needs to be widely distributed, regarding the availability and characteristics of disposal facilities around New Zealand.
